• Controller 1 – Assign all logical drives to Controller 1
• Controller 2 – Assign all logical drives to Controller 2.
• Automatic – Alternate logical drive assignments between Controllers 1 and 2.
Automatic is the default and preferred setting because it balances the logical drive assignments for you.

nitiAlizAtiOn
Initialization is done to logical drives after they are created from a disk array. Full initialization sets all data bits
in the logical drive to a specified pattern, such as all zeros. The action is useful because there may be residual
data on the logical drives left behind from earlier configurations. For this reason, Initialization is recommended
for all new logical drives. See “Initializing a Logical Drive” on page 206.

OrMAt
Like any other type of fixed disk media in your system, a RAID logical drive must also be partitioned and
formatted before use. Use the same method of partitioning and formatting on an logical drive as you would any
other fixed disk.
Depending on the operating system you use, there may or may not be various capacity limitations applicable
for the different types of partitions.
Caution
When you initialize a logical drive, all the data on the logical drive is
lost. Backup any important data before you initialize a logical drive.
